Application filed January '2, 191-7. Serial No. 14am. 7

To all whom it may concern:

Be it known that I, JAMES L. KnLLY, a citizen vof 'the United States, residing at Nowata, in the county of Nowa-ta and State of Gklahoma, have invented certain new and useful Improvements in Air-Feeding De- ,vices'for Internal-Combustion Engines; and

I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 1 i

This invention relates to improvements 1n attachments for internal combustion eng nes, particularly means for feeding heated air to the combustible mixture on its way to the cylinders.

The main object of the invent on 1s 3 vide a simple and efficient corg h m elem whereby e a; may be fed into the intake mu 'lf ldot an internal combustion engine 111' varying quantities.

An addltlonul ob ject is to rovide a device ;of thischaracter w ich can e very quickly and easily attached to practically any type of. internal combustion engine.

\Vith these and other objects in view, the. invent1on resides in the novel feature flof.

construction, combination and krrangeinent of parts which will be hen-zinaftcr more particularly set forth in the following specificationand claim.

In the accompanying drawings:

Figure 1 a side elevation of a portion of an internal combustion engine showing my improved air feeding mechanism attached I thereto;

Fig. 2 is an end view of the partsshown in Fig. 1, a portion of the air feeding means bemg in section;

Fig. 3 is a detail perspective view of the l heater from which heated air is supplied to the intake manifold of the engine;

'Fig. 4 is a detail perspective view showing one end of the operating rod. and its relation ate, the latter being secured to a. ortionof the dashboard of the vehicle. p ile this invention is designed particularl for use on automobile engines, it is 9 obvlous that it may be readily used on any other type of internal combustion engines. Y In the present instance, it is shown applied to an engine of conventional design desigjnated by the letter E which is formed of a number of cylinders-1, the combustible'mix .turebeing fed to said cylinders from the carstantially horizontal. It will be noted. that the engine illustrated has both the intake and the exhaust manifolds on thesame side thereof, but when they are on the opposite sides, the invention is slightly modified to accommodate this change.

As hereinhefore mentioned, the i consists of means for heati i d f df-Z the 553mg to illlntake manifold between the d js l. and the carburetor C. In fffng out this idea, a heater comprising a re thcr long open ended tube 5 is provided. said tubeheing positioned longitudinally of the exhaust manifold 4 in engagement therewith and also in contact with the side of the engine E. In most instances, the exhaust manifold is in the form of a round pipe and since it is disposed in close proximity to the engine cylindcln, a natural seat is provided 1 for the tube 5. -if'he ends of this tube are in tcrnau threaded and closed by means of screw plugs Air, however, can enter said tube thi'oiigh ,a pair of inlet openin s 7, one being disposed adjacent each end and formed in the side nearest the manifold 4. This causes air to be drawn from between the exhaust ma n.1fold and. the engine into the tube;

thus the air is slightly heated before it enters said tube. V

In the construction illustrated, the tube a is positioned on top of the exhaust manifold,

the openings 7 therein being disposed down wardly, and an outlet opening is formed substantially midway the ends and in a plane at right angles to aplane passing through.

the openings 7-. The last-mentioned opening 'is formed in the'outer side of the tube and is The T coup mg is inverted as illustrated in the drawings and the oppositeends thereof each carry a pipe 12, the outer end of -each of which is reduced as shown'at 13.-

These reduced ends '13 receive theuppei ends of flexible tubes-14%) which the 2, the flow of'heated air from said tube being controlled, as hereinbefore mentioned, by the valve 9.

Since the above described mechanism is disposed beneath the hood of an automobile when, the device is used on the engine there of, means must be provided for operating the valve 9 from the drivers seat. This is ascomplished by the rod 16 which has one end bent laterally as shown at 17 and disposed in the e e 18 -of the plug of said stop cook, the, otherend being extended through the'dash board oflth'e ehicle and rotatably' mounted therei adjacent the steering post of the vehicle; The upper end of the rod 16 is prpvided with a handle 19 so that upon rotatlon thereof, the plug of the stop cock will'be moved .to throw the opening therein into or out of registration with the openings in the sides of'the valve. The stop cock and the operatingrod 16 connected to the'plug thereof may be dises with respect to the outlet opening, removable caps closmg the posed at various ang other parts of the lnventionin order that they can be efiectively operated from the drivers seat as above mentioned.

The handle 19 of the rod 16 is formed by bending the free end of said rod upon itself as shown particularly in Fig. 4, and is adapted to coact with a locking plate 25 so as to hold the valve in open or closed osition. The locking plate 25 has an attac ing flange 26 by which the same is secured to a suitable portion of. the dash D of the ye- 'hicle, and a flange 27 whose outer edge is arcuate and provided with a plurality of notches 28, said notches being en ged by a portion 19 of the handle, Said flange 27 is also provided with an opening 29 to receive the rod 16', said opening beingthe center of the arcuate edge of the plate. The parts of the handle 19 will have sufiicient resiliency to permit the end 19 to readily spring into or out of any one of the seats formed by the notches 28, so that the valve may be readily held in any desired position yokes 20.

' w1tnesses.

so as to control the flow of heated air from the tube 5 to the intake manifold.

Althou h any preferred means may be used for olding the tube 5 in position on the exhaust mamfold, the device shown con air of substantially U-shaped sists of a ach of these yokes has its lower end 21 curved to conform to the curvature of the under side of the exhaust manifold, the upper end, however, being straighter as shown at 22, said upper end having a threaded aperture to receive a set screw 23. Upon placing one of these yokes 20 adjacent each end of the 'tube, engaging the ends 21 with the under side of the exhaust manifold, and then tightenin the set screw 23, the heater will be eflective y held against movement.

The purpose of supplying heated air to the combustible mixture of an internal combustion engine is well known in the art to which this invention relates, and therefore, I do not claim this broadly. 7 It is desired to call particular attention, however, to the simple improved formation of the parts and their relation to the intake and exhaust bustion engines ormed principally of pipe fittings and comprising a straight one-piece pipe having an inletv opening and a central ends of said pipe,meansfor clamping said connection with the branches of an intake manifold.

In testimony whereof I have hereunto set my hand in the presence of two subscribing JAMES L. KELLY.
